Abstract : Applying the momentum threshold autoregressive M-TAR model due to Enders and Granger 1998, this paper examines the relationship between the various prices of wheat quoted at different market centers in four Indian states. We find evidence of M-TAR asymmetric adjustments of wheat prices, indicating that price signals within states are transmitted over time in an asymmetric manner. This type of price adjusting behavior is consistent as to how price differentials may respond to poor dissemination of knowledge regarding market conditions and high transactions costs. The results offer important policy implications.
